The Goodman 10135604 Relay is a genuine OEM replacement component engineered specifically for the Goodman ASH130181AB heat pump and compatible condensing units. This relay manages the switching of electrical loads within the control circuit, energizing the compressor, fan motor, or reversing valve on command from the thermostat. A failing relay is a common cause of a system that won't start, short-cycles, or leaves the outdoor unit running when it should be off.
This is a true Goodman OEM part built to the exact electrical rating, coil voltage, and contact configuration the ASH130181AB was designed around. Generic universal relays may carry similar ratings but can differ in mounting footprint, terminal orientation, and switching timing — leading to nuisance faults or a physically awkward install. Choosing OEM protects your compressor and preserves manufacturer tolerances.
Easy to Moderate. A qualified technician can swap this relay in 15–30 minutes. Always disconnect power at the breaker and confirm zero voltage before servicing. Photograph the wiring before removal and transfer leads one at a time to avoid errors. If you are not comfortable working with high-voltage HVAC controls, contact a licensed HVAC professional.
